[PATCH] Reset grub_errno after embedding test on non-fatal failures

[Mario Limonciello]

Hello,

In additional MinGW testing, i've found that there are instances where the 
embedding test used in grub-setup will fail to seek on certain devices (such as 
card readers where no cards are physically present).  This sets grub_errno 
during the embedding test as the different disks in the system are tested.  It 
gets set even when installing to a different disk (all the physical disks are 
seeked).  Consequently grub_errno remains set up to the point when the core 
image is to be written out and mistakingly will indicate grub-setup failed for 
a seek error that happened at the start.

So this patch resets grub_errno while completing the embedding test only on the 
non fatal failures.

Thanks,
